Nozzle Cluster

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a novel nozzle cluster (Düsencluster) composed of multiple pairs of gas outlet openings: each pair includes a first opening for a fuel gas (such as hydrogen) and a second opening for an oxidizing gas (such as air), with the latter at least partially surrounding the former. This design allows the two gases to remain separated until immediately before or at the point of exit, facilitating controlled mixing and combustion. It is particularly suited for uses such as burners in gas turbines or chemical mixers, and can be manufactured efficiently using additive manufacturing (3D printing).

Use CasesContent extracted from patent full text and abstract with AI.

• Burners for industrial or power generation applications (e.g., hydrogen or syngas burners)
• Gas turbines for electricity generation employing low-emission combustion
• Mixers for chemical processes involving controlled gas or gas-liquid mixing
• Porous burners in heating systems needing clean and efficient fuel combustion
• Flexible, modular burner arrays in scalable energy systems
• Production of flame arresters or safety devices for combustible gas handling

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly reduces the risk of flashback (flame propagation upstream), increasing operational safety
• Allows for very low emissions, especially reduced NOx due to controlled mixing and cooler operation
• Supports flexible and modular scaling by simply increasing the number of nozzle pairs
• Enables fine control over the mixing and combustion process, supporting a wide range of operating conditions
• Provides the potential for simple, cost-effective manufacturing via 3D printing, including complex or customized geometries
• Simplifies maintenance and inspection with designs allowing for easy assembly/disassembly
• Reduces the requirement for expensive high-temperature materials because of self-cooling effects
• Applicable to both gas and liquid mixing, increasing versatility for industrial applications
